- Based on the results from Study 1, the largest percentage of moths in City Y and City Z had a color intensity of:
City Y City Z
A. 8 1
B. 8 5
C. 9 4
D. 9 5
- During which of the following years was birch bark most likely to be thickest in City Y ?
F. 2000
G. 2001
H. 2002

- How was Study 1 different from Study 2 ?
A. B. betularia f. carbonaria moths were captured in Study 1 but not in Study 2.
B. B. betularia f. typica moths were captured in Study 1 but not in Study 2.
C. The moth body coloration was measured in Study 1 but not in Study 2.
D. The moth body coloration was measured in Study 2 but not in Study 1.
- The scientists most likely labeled the moths in Study 1 to:
F. determine how body coloration was affected by pollution in City X.
G. determine the average wingspan of each population of moths.
H. make sure that the body coloration of each moth was measured only once.
J. make sure that the body coloration of each moth was measured multiple times.
